Griffin appeared to aggravate his right knee injury late in the first quarter during a rollout that led to an incomplete pass. After throwing a 4-yard touchdown pass on the next play, Griffin limped back to the sideline and was sent to the locker room by Redskins coach Mike Shanahan.

Griffin rejoined his teammates a short time later and was seen sitting on the bench looking over plays with offensive coordinator Kyle Shanahan while the Redskins' defense was on the field. Griffin returned for Washington's next series, but he clearly wasn't moving well.

Griffin is wearing a large brace on the knee he originally injured against the Baltimore Ravens in Week 14. Griffin completed 6 of 9 passes for 68 yards and two touchdowns in leading the Redskins to a 14-0 lead through one quarter.

Dr. James Andrews -- the famed orthopedic surgeon who has been on the Redskins' sideline this season -- said he has been a "nervous wreck" watching Griffin come back to action as quickly as he has. Andrews denied the report he cleared Griffin to return to the field after he originally injured the knee Dec. 9.
